AMD Ryzen 5 PRO 8645HS vs Intel Core 5 330 Comparison

Head-to-Head Benchmarks

The head-to-head results are decisively lopsided. The AMD Ryzen 5 PRO 8645HS wins 14 of the 17 recorded comparisons, while the Intel Core 5 330 takes only 3. The margin in most multi-threaded workloads is enormous.

In Cinebench, the AMD part dominates every test. In R15 multicore, it scores 1989 against 1325, a 50.1% lead. The single-core R15 result is similarly one-sided: 280 versus 186, a 50.5% advantage. Moving to R20, the AMD chip posts 8291 versus 5523 in multicore (50.1% ahead), and 1170 versus 779 in single-core (50.2% ahead). The R23 results follow the same pattern: 19742 versus 13150 in multicore (50.1% lead) and 2787 versus 1856 in single-core (50.2% lead).

The Passmark suite shows where the AMD processor's architecture pulls away. Integer math is the largest gap: 72740 versus 33258, a 118.7% advantage. Random string sorting also shows a massive difference, with the AMD chip scoring 35472 against 17771, a 99.6% lead. Data compression favors AMD at 265826 versus 145287, an 83% margin. Data encryption goes to AMD at 17387 versus 11076, a 57% gap. Extended instructions follow with 21212 versus 12808, a 65.6% difference. Multithread performance lands at 23569 versus 15471, a 52.3% lead.

The Intel Core 5 330 wins only three tests. Find prime numbers is its strongest result: 114 versus 73, meaning the Intel part is 36% ahead there. It also wins both single-thread Passmark entries, scoring 4088 against 3858, a 5.6% margin. It is important to note that this Passmark single-thread win does not align with the Cinebench single-core results, where AMD was far ahead. The two benchmarks clearly measure different aspects of single-thread performance.

Two other tests are close enough to note. Floating point math favors AMD only slightly, 45481 versus 43885, a 3.6% edge. Physics is nearly identical, with AMD ahead by 0.6% (1208 versus 1201). These are the only results where the two processors are effectively tied.

Architecture Differences

The two CPUs come from fundamentally different design philosophies. The AMD Ryzen 5 PRO 8645HS uses Zen 4 architecture on the Hawk Point codename, built on a 4 nm TSMC process. It has 6 cores and 12 threads, meaning each core can handle two threads simultaneously. The Intel Core 5 330 uses Wildcat Lake architecture on a 3 nm Intel process, and it also has 6 cores but only 6 threads, so it lacks simultaneous multithreading entirely.

Clock speeds show a major divergence. The AMD chip has a base clock of 4.30 GHz and a boost clock of 5.00 GHz. The Intel part has a base clock of 1.50 GHz and a boost of 4.60 GHz. The AMD processor runs at a much higher sustained speed, which explains much of its multi-threaded advantage despite both having 6 cores.

Cache configurations differ substantially. AMD uses a per-core layout: 64 KB of L1 per core, 1 MB of L2 per core, and 16 MB of shared L3. The Intel part lists a total L1 of 192 KB, 2.5 MB of L2, and 6 MB of shared L3. The AMD chip has far more total cache, and its L3 is nearly three times larger.

The process nodes differ as well. AMD uses TSMC's 4 nm node with a die size of 178 mm² and 25,000 million transistors. Intel uses its own 3 nm process, though transistor count and die size are not recorded in the database. The Intel part is a single-channel memory design while AMD uses dual-channel memory. Memory bandwidth reflects this: AMD reaches 89.6 GB/s, Intel reaches 59.7 GB/s. AMD supports DDR5 and ECC memory; Intel supports DDR5 and LPDDR5X but no ECC.

Integrated graphics differ. The AMD chip uses Radeon 760M, while Intel uses Xe3 Graphics with 2 Xe cores. PCIe lane counts are also different: AMD provides Gen 4 with 20 lanes from the CPU, Intel provides Gen 4 with only 6 lanes.

Where Each One Wins

The AMD Ryzen 5 PRO 8645HS wins in nearly every workload that stresses multiple cores or sustained throughput. Cinebench multicore results show a 50% lead across all three versions, confirming that the 12-thread design with high base clocks scales effectively. Integer math, data compression, encryption, and random string sorting all favor AMD by large margins, making it the clear choice for database work, compression tasks, encryption workloads, and any parallel compute. The multithread Passmark result at 23569 versus 15471 confirms this pattern.

The Intel Core 5 330 wins in two specific areas. Prime number finding is markedly better, with a 36% advantage. That test likely benefits from the higher per-core frequency behavior under certain instruction patterns or from the newer process node's efficiency. The Passmark single-thread score also favors Intel, 4088 versus 3858, which indicates that in some single-threaded scenarios the Intel core design can outpace the AMD core, even though Cinebench single-core tests tell the opposite story.

The close results in floating point math and physics suggest that for scientific or physics-simulation workloads, the two CPUs are effectively interchangeable. The AMD chip is only 3.6% ahead in floating point and 0.6% ahead in physics, which is within noise for many real-world uses.

The Verdict

The benchmark data points to a clear performance hierarchy. The AMD Ryzen 5 PRO 8645HS is the faster processor across the overwhelming majority of tests, with a 50% lead in every Cinebench multi-core test and more than double the integer math score. Its 12 threads, higher base clock, larger L3 cache, and dual-channel memory controller all contribute to this result. The 45 W TDP indicates it is designed for sustained performance in a mobile chassis that can handle the heat.

The Intel Core 5 330 is a lower-power part at 15 W, and the data shows it wins only in prime number finding and one single-thread Passmark test. Its 3 nm process and newer release date do not translate into a multi-threaded advantage. For workloads that rely on parallel execution, compression, encryption, or large data movement, the AMD chip is the stronger choice based on the recorded measurements. The Intel part's wins are narrow and specific, not general.

The average benchmark score difference is substantial: 30879 for AMD versus 18345 for Intel. The AMD chip sits at the 82nd percentile among all CPUs, while Intel sits at the 72nd percentile. The nearest rivals for AMD include the AMD Ryzen 7 8700F, Intel Core i7-13700TE, AMD Ryzen 9 8945HS, and Intel Core i7-12700F, all within 0.6% of its average score. The Intel Core 5 330 sits near the Intel Core i3-14100, Intel Core 7 360, Intel Core i3-13100, and Intel Core 3 305, all within 0.2%. The launch MSRP for the Intel chip is $309; the AMD chip has no recorded launch MSRP.

Select the AMD Ryzen 5 PRO 8645HS for multi-threaded productivity, content creation, or any workload that scales across many threads. Select the Intel Core 5 330 for low-power mobile designs where prime number finding or the specific Passmark single-thread workload matters, and where the 15 W thermal envelope is a requirement.
